a(n) = 1 + 7(n-1)
Step-by-step explanation:
 
        
             
        
        
        
For this case we have the following equation:

If we multiply both sides of the equation by 3 we get:
 ---> Multiplication Property of Equality
 ---> Multiplication Property of Equality
Applying the distributive property we have:
 ---> Distributive Property
 ---> Distributive Property
Adding 1 on both sides of equality we have:

 ---> Addition Property of Equality
 ---> Addition Property of Equality
Subtracting  on both sides we have:
 on both sides we have:

 ---> Subtraction Property of Equality
 ---> Subtraction Property of Equality
Finally, dividing by -4 on both sides we have:

 ---> Division Property of Equality
---> Division Property of Equality
 
        
                    
             
        
        
        
(3/5)(2/5)=6/25

Answer: Rational
Step-by-step explanation: 12 is a rational number because it can be expressed as the quotient of two integers: 12÷ 1
 
        
             
        
        
        
Answer:
A) 5
Step-by-step explanation:
distance = √(distance between x coordinates² + distance between y coordinates²)
the horizontal distance between the two points is 4
the vertical distance between the two points is 3
to prove this, if you started at Q and went 4 points right and then 3 points up, you would get to P
distance = √(4²+3²) = √25 = 5
